Is an electric superheater radiant or convective?

[vishnu123]

Hello everyone,
I am dynamically modelling a electric superheater. During the calculation I need to calculate the overall heat transfer coefficient. Can someone tell me which calculation do I need to use to calculate the overall heat transfer coefficient, radiant or convective?
Please clear my mind.
With regards

Hello again,

What kind of superheater ? How do you intend to transfer the electric energy to the vapour phase ?

And remind us whether this was for batch or for continuous flow.

sorry for the link, i have deleted it and will upload the clear view of the boiler

Is this the same project ? I haven't found your clear view yet ...

Hello all,
I am planning to use a tubular heating elements for heat transfer, unlike the readily available electric superheaters now. I am not concerned about the physical design parameters. The flow is continuous.
with regards

I suspect Vishnu is only modelling ...

Is this a continuation of your earlier thread?

Hello all,
something like an extension of my previous work on boiler and an single effect steam evaporator has been added and the steam generated has to be superheated.
